The purpose of this utility model provides a kind of comparatively desirable chair and desk for pupils, it can regulate height of table top, seat height and position, has adjustable rumpbone to prop up and leans on, movable holder bookshelf, roomy pencil box, make every effort to good looking appearance firm in structure, become the strong assistant in the students study.

The purpose of this utility model is achieved in that a cover suitably desk and the chair of size, the pin that two inverted T-shapeds are respectively arranged, be connected with the top differing heights by screw, realize the height adjusting of desktop, seat, chair back bottom is established rumpbone and is propped up and lean on, this rumpbone prop up by and seat can regulate respectively up and down and front and back position.Seat recedes 3～10 °.The leading portion of the desktop in face of the student is the plane, and left front and right front desktop can be uncovered respectively, exposes following ad hoc pencil box, and right front desktop is uncovered, and oblique cutting also can hold in the palm bookshelf in the left front.The little gradient (10 °～15 °) that the oriented student's direction of the back segment of desktop tilts, back desktop can be uncovered, and is the school bag case below the desktop.

The both feet of the cross bar of the inverted T-shaped of tables and chairs are welded into by square steel pipe, and connecting portion has also been set up the bearing diagonal rib.The cross bar of inverted T-shaped crouches on the ground, the two ends that contact with ground are stained with rubber blanket, and the straight-bar of inverted T-shaped is in the square hole that the groove of insertion table skeleton and table side plate constitute, groove is made of troughing plate, to leaving a slotted hole, there is screw the straight-bar upper end of inverted T-shaped at the suitable upper and lower of the bottom portion of groove of table skeleton, and the slotted hole that has screw to pass the bottom land on the skeleton is screwed into screw, housing screw, height of table top is promptly fixing, changes the upper-lower position of screw in groove, can regulate height of table top.The adjusting of seat is similar to desktop, and difference only replaces troughing plate for the chair skeleton with angle steel, and chair does not have side plate, does not constitute square hole, only leans on mutually with rectangular steel tube with angle steel two medial surfaces, on the angle steel face, replaces elongated slot at the uniform some screw holes of different up and down height.

Seat and rumpbone prop up by being made of plank bottom, foam plastics core, soft shell fabric.The plank bottom embeds metal nuts, on the chair skeleton with seat and rumpbone prop up the plank bottom that leans on contact have respectively on the plain plate forward and backward and upper and lower to slotted hole, hold-down screw passes slotted hole, is screwed in the nut of plank bottom, regulates and is fixed after putting in place.

The book legs are mainly held in the palm by means of two as the holder bookshelf in right front desktop oblique cutting left front.Every holder book leg is formed by an iron wire bending, and at first, iron wire bending two limits at an angle, a hole of passing the desktop back side, its termination are bent into " U " font, and the termination on another limit then is bent into " Z " shape.Iron wire after the bending still is in the same plane.During as right front desktop, holder book leg invests under the desktop parallel with desktop, can too much not dwindle following pencil box space; During as the holder bookshelf, right front desktop can be uncovered, two holder book legs are moved in the hole at the desktop back side, make " U " font hook of termination surpass the desktop edge, half-twist then, again the termination of iron wire other end ＂ Z ＂ font is inserted in the corresponding hole of left front desktop, can insert books in the ＂ U ＂ font hook, make page holder constant.

Desktop slightly tilts, and table side plate upper end is wide, and the lower end is narrow, one side near user's the neutral of reserving, provide convenience for the turnover of user's thigh in the lower end, approximate piano has increased attractive in appearance on the profile.

The desktop width can have two kinds that are fit to single use and double use, and double type desktop is widened one times.The inverted T-shaped pin of desk still adopts two, is used in the more apparent saving of school.
